* Basic transactions set up (to be separated) * Change transaction command to not include create operation (to include other command in next commit) * set up create command and made minor changes * wip implements module queries * Added tests for query address decoding * Added ambiguous encoding of to address in transaction and added tests * Fix linting issue * Move registering key types to application level to allow module usage to ignore * Move genaccounts code to be reused * Switches nonce increase to always happen in ante handler * change SetNonce from keeper to point to actual nonce operation * Remove no op nonce switch (not needed with clearing cache) * Changes to update all accounts pre state transition and clear cache at end of block * Update accounts before end of block commit (edge case where necessary) * Fix nonce of sender going into evm in case it's checked, and let evm set contract starting nonce |

Ethermint
WARNING: Ethermint is under VERY ACTIVE DEVELOPMENT and should be treated as pre-alpha software. This means it is not meant to be run in production, its APIs are subject to change without warning and should not be relied upon, and it should not be used to hold any value. We will remove this warning when we have a release that is stable, secure, and properly tested.
What is it?
ethermint will be an implementation of the EVM that runs on top of tendermint consensus, a Proof of Stake system. This project has as its primary goals:
- Hard Spoon enablement: This is the ability to take a token from the Ethereum mainnet and "spoon" (shift) the balances over to another network. This feature is intended to make it easy for applications that require more transactions than the Ethereum main chain can provide to move their code over to a compatible chain with much more capacity.
- Web3 Compatibility: In order enable applications to be moved over to an ethermint chain existing tooling (i.e. web3 compatible clients) need to be able to interact with
ethermint.
Implementation
Completed
- Have a working implementation that can parse and validate the existing ETH Chain and persist it in a Tendermint store
- Implement Ethereum transactions in the CosmosSDK
Current Work
- Implement web3 compatible API layer
- Implement the EVM as a CosmosSDK module
- Allow the Ethermint EVM to interact with other Cosmos SDK modules
Next Steps
- Hard spoon enablement: The ability to export state from
gethand import token balances into Ethermint - Ethermint is a functioning Cosmos SDK application and can be deployed as its own zone
- Full web3 compatibility will enable existing Ethereum applications to use Ethermint
Building Ethermint
To build, execute the following commands:
# To build the binary and put the resulting binary in ./build
$ make tools verify build
# To build the project and install it in $GOBIN
$ make tools verify install
Tests
Integration tests are invoked via:
$ make test
To run CLI tests, execute:
$ make test-cli
Ethereum Mainnet Import
There is an included Ethereum mainnet exported blockchain file in importer/blockchain
that includes blocks up to height 97638. To execute and test a full import of
these blocks using the EVM module, execute:
$ make test-import
You may also provide a custom blockchain export file to test importing more blocks
via the --blockchain flag. See TestImportBlocks for further documentation.
